Fused Glass from Tropics of Costa Rica

Hot glass will find it’s own level

what to do in samara costa ricaSaturday’s Beginning Glass Fusing produced some lovely pieces by four first-timers.  It also produced some interesting lessons.

When melted and allowed to flow freely, glass “wants” to be 1/4″ thick.  With enough heat, the mass of molten glass will expand or contract until it is 1/4″ thick.  Each of these designs was laid up on a 6″ x 6″ piece of 1/8″ clear glass (System 96).  But some changes occurred in the kiln.

shrunk in the kiln, pushing the glass to the center as it tried to get thicker.

This design has some very thick detailing in two corners, which expanded upon firing.

The other corners, with two layers of glass, stayed pretty square.

With a continuous border of very thick glass,

this design expanded about 1/2″ but quite evenly and retained a fairly square shape.

This design completely covered the base glass with a collage of 1/8″ thick glass.

The result after firing is about the same size and shape as the original 6″ square.  A few thicker details in the center of the piece found room to settle before pushing the edges out.

  1. Lavae, I’m so envious. How I’d love to be there and take all your lessons. I’ve always
    wanted to work in glass. (so did U. Ralph) And you are a master at mass adveritising.

    • I didn’t know you were both interested in glass. But maybe I did. Maybe, you gave me a subliminal message, to foster my own desire.
